"We approached Gordon and Tana Ramsay after the premature birth of their twins in 1999," says Jane Brewin, chief executive of Tommy's. "Gordon ran two consecutive London Marathons for us and is a family man who continues to support our cause passionately."
Ramsay says: "Tommy's is very close to my heart, especially because my own twins were born three weeks prematurely.
"It was an emotional and strained time for the family, but we were lucky and the twins pulled through. It's awful to think that other parents go through similar traumas each day in the UK.
"With further funding for their essential research, Tommy's aims to end this heartache, which is why I support its worthy cause."
Bob Geldof, the musician and driving force behind the Band Aid and Live 8 concerts, presented a cheque for £10,000 to Missing People in London earlier this month.
Geldof presented the cheque to Paul Tuohy, chief executive of Missing People, in his role as founding partner of Groupcall, a company that provides text and voice messaging services for schools in an effort to reduce truancy. The company has launched a partnership with the charity and will donate 10 per cent of the value of all new Groupcall Messenger subscriptions.
"Missing People is a charity that does so much for young runaways, missing and unidentified people, their families and those who care for them," says Geldof.
"Groupcall provided me with reassurance that my daughters had arrived at school safely after a journey across London. We hope to assist Missing People in its continued search for all those who are missing."
